DETAILED DESCRIPTION OF EMBODIMENTS OF THE PRESENT INVENTION

Embodiments of the present invention are described in detail with reference to the accompanying drawings.

In the following description, the same or similar reference numerals may be used for the same or similar elements when they are illustrated in different drawings. Detailed descriptions of constructions or processes known in the art may be omitted to avoid obscuring the subject matter of the present invention.

FIG. 1 is a diagram illustrating a screen of a display apparatus 100 according to an embodiment. Referring to FIG. 1, a digital content generating window 110 on which an inputted image is presented, is displayed on the screen of the display apparatus 100.

The ‘inputted image’ herein is in a base template or form of the digital content. The inputted image includes a plurality of intermediary figures and thus is applied as the base forms to generate digital content. The intermediary figures will be explained in detail below.

The display apparatus 100 may receive an input in various manners. Specifically, the display apparatus 100 may receive from an external photographing apparatus an image taken by the external photographing apparatus. The external photographing apparatus herein may be implemented as one of digital camera, wired/wireless webcam, portable camera, camcorder, object image processor, or scanner. Accordingly, if the display apparatus 100 receives an image photographed by the external photographing apparatus, user may hand-draw a base image for digital content, photograph the hand-drawn image using the external photographing apparatus, and input the photographed image to the display apparatus 100. Then, the user may create an image incorporating a plurality of intermediary figures by hand-drawing the intermediary figures properly. As a result, the user can easily create an image as a basis for the digital content.

The display apparatus 100 may receive a base image for digital content based on an image stored at a built-in storage medium. Accordingly, the user may load frequently-used image and use the loaded image easily. The display apparatus 100 may also receive an image stored at an external device from the external device.

The display apparatus 100 may also receive an image drawn by user touch. By way of example, the display apparatus 100 may receive an image drawn on the touch screen by the user and use the received image as a base image for the digital content. Additionally, the display apparatus 100 may receive an image drawn on the touch screen of the external device from the external device and use the received image as a base image for the digital content.

The display apparatus 100 may also convert a document file, which is written by a document writing program of a computer such as PowerPoint or word processor, and apply the converted image file as the base image for the digital content.

As explained above, the display apparatus 100 may receive an inputted image in various manners. And as illustrated in FIG. 1, the inputted image is displayed on the digital content generating window 110.

The display apparatus 100 also perceives the intermediary figure included in the inputted image. Referring to FIG. 1, the image appearing on the digital content generating window 110 may include a first intermediary FIG. 120, a second intermediary FIG. 130, and a third intermediary FIG. 140. Accordingly, the display apparatus 100 perceives that the inputted image includes the first, second and third intermediary FIGS. 120, 130, 140.

The intermediary figure corresponds to a location to which a digital object is to be inserted. The display apparatus 100 perceives the intermediary figures included in the inputted image, and inserts the digital object to the locations where the intermediary figures are displayed according to user selection. Specifically, the intermediary figures may include at least one of specific pattern, specific text, specific shape, and specific video.

Referring to FIG. 1, the first intermediary FIG. 120 may be a box pattern with a letter X formed therein, the second intermediary FIG. 130 may be a box with a letter P formed therein, and the third intermediary FIG. 140 may be a box with a letter M formed therein.

As explained above, there may be a plurality of intermediary figures, and the display apparatus 100 inserts different types of digital objects depending on the respective types of the intermediary figures. That is, the types of intermediary figures represent the types of to-be-inserted digital objects. By way of example, the first intermediary FIG. 120 corresponds to a location to which a text object related with a title is inserted. The second intermediary FIG. 130 corresponds to a location to which a photograph object is inserted. The third intermediary FIG. 140 corresponds to a location to which a video object is inserted. As explained above, which digital objects are inserted to the locations of the intermediary figures depends on the types of the intermediary figures.

The user may arbitrarily change the types of digital objects that correspond to the intermediary figures. Additionally, the user may set a new intermediary figure, and also designate a digital object that corresponds to the newly-set intermediary figure.

Herein, the ‘digital object’ refers to a certain type of sub-content which is inserted into an image inputted to generate digital content. The types of digital objects may include at least one of an image, video image, media file, text file, text input window, shapes, link information, widget, and application program. The types of digital objects inserted into the intermediary figures are determined according to the types of the intermediary figures.

Additionally, the display apparatus 100 may perceive the intermediary figures included in the inputted image by automatic or manual recognition. Specifically, if automatic recognition is set for the recognition of the intermediary figures, the display apparatus 100 perceives the intermediary figures included in the inputted image automatically upon input of the image. However, if the manual recognition is set for perceiving the intermediary figures, the display apparatus 100 perceives the intermediary figures included in the inputted image upon receipt of a user command directing to perceive the intermediary figures.

The display apparatus 100 inserts a digital object selected by the user into a location where the intermediary figure is displayed. Specifically, the display apparatus 100 displays a list of a plurality of digital objects to be inserted, upon receipt of a user command directing to insert the objects with respect to the intermediary figures included in the displayed image. That is, the display apparatus 100 displays on the screen a list of specific types of digital objects that correspond to the types of the intermediary figures, upon receipt of a command directing to insert an object with respect to a specific intermediary figure. By way of example, in response to a command directing to insert an object with respect to the second intermediary FIG. 130, the display apparatus 100 displays a list of image files which can be inserted. If a command directing to insert an object with respect to the third intermediary FIG. 140 is inputted, the display apparatus 100 displays a list of insertable video files.

The display apparatus 100 then inserts a digital object selected by the user from among the plurality of digital objects of the digital object list into a location where the intermediary figure is displayed.

If the user inserts a command directing to insert an object with respect to the intermediary figure included in the displayed image, the display apparatus 100 may display a Digital Object Type menu. The ‘Digital Object Type menu’ herein may include an image item, a video item, and a text item.

The display apparatus 100 displays a list of digital objects of the type as selected by the user from the Digital Object Type menu. By way of example, if the user selects an image item from the Digital Object Type menu, the display apparatus 100 displays a list of images which can be inserted into a location where a corresponding intermediary figure is displayed. If the user selects a video item from the Digital Object Type menu, the display apparatus 100 displays a list of video images which can be inserted into a location where a corresponding intermediary figure is displayed.

The display apparatus 100 may also drag & drop a digital object displayed on a background screen to insert the digital object into a location where the intermediary figure is displayed.

The display apparatus 100 inserts digital objects into a plurality of intermediary FIGS. 120, 130, 140 displayed on the digital content generating window 110 and thus stores and displays the completed digital content. That is, the ‘digital content’ refers to the content which is completed as the digital objects are inserted into an inputted image.

The display apparatus 100 re-sizes the digital object to suit the size of the intermediary figure before inserting the digital object into the intermediary figure. Accordingly, the size of the intermediary figure corresponds to the size of the digital object after insertion. However, the display apparatus 100 may insert a digital object into an intermediary figure while maintaining a predetermined horizontal to vertical ratio of the digital object. Additionally, as the user selects, the display apparatus 100 may determine whether to insert the digital object in the size of the intermediary figure or in its original size.

As explained above, the display apparatus 100 may scale-down the digital object automatically or according to user selection, if the digital object to be inserted has a different size.

Additionally, the display apparatus 100 may generate digital content in a manner of grouping an inputted image and an inserted digital object together. That is, since the digital object and the image of the digital content form a group, the digital object changes size as the digital content changes size.

The display apparatus 100 may also un-group the digital content including the inputted image and the inserted digital object, according to user selection. If the digital content is un-grouped, the display apparatus 100 may change the location or size of the digital object of the digital content only, or remove the digital object from the digital content.

As explained above, the user is able to generate digital content easily, by simply inserting digital object through touch screen or the like based on hand-written image or previously-written image.

Accordingly, the display apparatus 100 inserts digital object into the intermediary figure according to the user selection, by automatically perceiving the intermediary figure included in the inputted image. As a result, the user can generate digital content by a simple operation, i.e., by inserting the digital object into a location where the intermediary figure is displayed.

FIG. 2 is a flowchart provided to explain a method for generating digital content according to an embodiment.

First, at 5210, the display apparatus 100 receives an image. The inputted image is applied as a template or form as a basis of the digital content. Since the inputted image includes a plurality of intermediary figures, the inputted image is applied as a base form of generating the digital content.

The display apparatus 100 may receive an input in various manners. Specifically, the display apparatus 100 may receive from an external photographing apparatus an image taken by the external photographing apparatus. The external photographing apparatus herein may be implemented as one of digital camera, wired/wireless webcam, portable camera, camcorder, object image processor, or scanner. An example where the image is received from a portable camera will be explained below with reference to FIGS. 3A to 3I, and an example where the image is inputted from an object image processor will be explained below with reference to FIGS. 4A to 4N.

Accordingly, if the display apparatus 100 receives an image photographed by the external photographing apparatus, user may hand-draw a base image for digital content, photograph the hand-drawn image using the external photographing apparatus, and input the photographed image to the display apparatus 100. Then, the user may create an image incorporating a plurality of intermediary figures by hand-drawing the intermediary figures properly. As a result, the user can easily create an image as a basis for the digital content.

The display apparatus 100 may receive a base image for digital content based on an image stored at a built-in storage medium. An example where the previously-stored image is inputted will be explained below with reference to FIGS. 5A to 5J. Accordingly, the user may load frequently-used image and use the loaded image easily. The display apparatus 100 may also receive an image stored at an external device from the external device.

The display apparatus 100 may also receive an image drawn by the user touch. By way of example, the display apparatus 100 may receive an image drawn on the touch screen by the user and use the received image as a base image for the digital content. Additionally, the display apparatus 100 may receive an image drawn on the touch screen of the external device from the external device and use the received image as a base image for the digital content. An example where an image is inputted based on the user touch selection will be explained in detail below with reference to FIGS. 6A to 6E and FIGS. 7A to 7E.

The display apparatus 100 may also convert a document file, which is written by a document writing program of a computer, and apply the converted image file as the base image for the digital content.

As explained above, the display apparatus 100 may receive an inputted image in various manners.

At S220, the display apparatus 100 displays the inputted image on the digital content generating window 110.

At S230, the display apparatus 100 perceives the intermediary figure included in the inputted image. The intermediary figure corresponds to a location to which a digital object is to be inserted. At S240, the display apparatus 100 inserts the digital object to the locations where the intermediary figures are displayed according to user selection. Specifically, the intermediary figures may include at least one of specific pattern, specific text, specific shape, and specific video.

There may be a plurality of intermediary figures, and the display apparatus 100 inserts different types of digital objects depending on the respective types of the intermediary figures. That is, the types of intermediary figures represent the types of to-be-inserted digital objects.

Herein, the ‘digital object’ refers to a certain type of sub-content which is inserted into an image inputted to generate digital content. The types of digital objects may include at least one of an image, video image, media file, text file, text input window, shapes, link information, widget, and application program. The types of digital objects inserted into the intermediary figures are determined according to the types of the intermediary figures.

The display apparatus 100 inserts a digital object selected by the user into a location where the intermediary figure is displayed. Specifically, the display apparatus 100 displays a list of a plurality of digital objects to be inserted, upon receipt of a user command directing to insert the objects with respect to the intermediary figures included in the displayed image. That is, the display apparatus 100 displays on the screen a list of specific types of digital objects that correspond to the types of the intermediary figures, upon receipt of a command directing to insert an object with respect to a specific intermediary figure. By way of example, in response to a command directing to insert an object with respect to the second intermediary FIG. 130, the display apparatus 100 displays a list of image files which can be inserted. If a command directing to insert an object with respect to the third intermediary FIG. 140 is inputted, the display apparatus 100 displays a list of insertable video files.

The display apparatus 100 then inserts a digital object selected by the user from among the plurality of digital objects of the digital object list into a location where the intermediary figure is displayed.

If the user inserts a command directing to insert an object with respect to the intermediary figure included in the displayed image, the display apparatus 100 may display a menu of digital object types. The ‘menu of digital object types’ herein may include an image item, a video item, and a text item.

The display apparatus 100 displays a list of digital objects of the type as selected by the user from the menu of digital object types.

At S250, the display apparatus 100 displays the digital content in which the digital object is inserted into the image. At S260, the display apparatus 100 stores the completed digital content as a separate file. The display apparatus 100 may also store the entire screen on which the completed digital content is displayed.

Additionally, the display apparatus 100 may generate digital content in a manner of grouping an inputted image and an inserted digital object together. That is, since the digital object and the image of the digital content form a group, the digital object changes size as the digital content changes size.

The display apparatus 100 may also un-group the digital content including the inputted image and the inserted digital object, according to a user selection. If the digital content is un-grouped, the display apparatus 100 may change the location or size of the digital object of the digital content only, or remove the digital object from the digital content.

As explained above, the user is able to generate digital content easily, by simply inserting digital object through touch screen or the like based on hand-written image or previously-written image.

Accordingly, the display apparatus 100 inserts digital object into the intermediary figure according to user selection, by automatically perceiving the intermediary figure included in the inputted image. As a result, the user can generate digital content by a simple operation, i.e., by inserting the digital object into a location where the intermediary figure is displayed.

FIGS. 3A to 3I illustrate the process of receiving an image photographed by a camera and generating content using the inputted image, according to an embodiment.

FIG. 3A illustrates the screen of the display apparatus 100. Referring to FIG. 3A, a first video object 311, a first photo object 312 and a second photo object 313 are currently displayed on the screen of the display apparatus 100.

At this state, if a paper sheet 320 as a basis for content is placed on the right side of the screen as illustrated in FIG. 3B, the display apparatus 100 perceives the location where the paper sheet 320 is placed and also the size of the paper sheet 320. The paper sheet 320 includes a first intermediary FIG. 321, a second intermediary FIG. 322 and a third intermediary FIG. 323.

Referring to FIG. 3C, the user photographs the paper sheet 320 using the camera 300. Referring to FIG. 3D, the camera displays the image 330 corresponding to the paper sheet 320 on the screen. If the user presses ‘send’ button 340, the camera 300 transfers the photographed image 330 of the paper sheet 320 to the display apparatus 100.

Referring to FIG. 3E, the display apparatus 100 displays the photographed image 330 on the digital content generating window 350. As illustrated, the display apparatus 100 displays the digital content generating window 350 in the same size as that of the paper sheet 320 and on the same location as the paper sheet 320.

Referring to FIG. 3F, the user can see the digital content generating window 350 displayed on the screen of the display apparatus 100 as he removes the paper sheet 320. The digital content generating window 350 displays the photographed image 330. And the photographed image 330 includes the first, second and third intermediary FIGS. 351, 352, 353 which are exactly the same as drawn on the paper sheet 320. Accordingly, when the photographed image 330 is inputted, the display apparatus 100 perceives that the photographed image 330 contains the first, second and third intermediary FIGS. 351, 352, 353.

Referring to FIG. 3G, by dragging & dropping the video object 311 from among the digital objects 311, 312, 313 displayed on the background screen into the third intermediary FIG. 353, the user can insert the video object 311 into a location where the third intermediary FIG. 353 is displayed.

FIG. 3H illustrates a situation in which the first photo object 312 is inserted into the first intermediary FIG. 351, and the video object 311 is inserted into the third intermediary FIG. 353, with respect to the image 330 displayed on the digital content generating window 350.

FIG. 3I illustrates a situation in which the first photo object 312 is inserted into the first intermediary FIG. 351, the second photo object 313 is inserted into the second intermediary FIG. 352, and the video object 311 is inserted into the third intermediary FIG. 353. Accordingly, if a save button 360 is touched in a state that the digital content is completed, the display apparatus 100 stores the completed digital content as displayed on the digital content generating window 100 as a separate file.

By the process explained above, the display apparatus 100 receives an image photographed by the camera and generates content using the inputted image. Accordingly, the user photographs a hand-drawn picture on a paper sheet with the camera and generates digital content on the display apparatus 100 based on the photographed picture.

Referring to FIGS. 4A to 4N, the process of receiving an image photographed by an object image processor and generating content using the inputted image will be explained below. FIGS. 4A to 4N illustrate the process in which an image photographed by the object image processor is inputted and content is generated using the inputted image. The object image processor herein refers to a device which photographs images of various objects and transfers the photographed images to the surrounding devices. The object image processor provides various additional functions and is widely used in many applications such as teaching equipment at a classroom. The object image processor is used mainly to display the content of books, printouts on a connected display apparatus 100 in an increased size. Since a lens is formed on an upper end of the object image processor, the object image processor transfers the image of any object that is placed under the lens to the display apparatus 100 at room brightness.

FIG. 4A illustrates the screen of the display apparatus 100 which is capable of communicating with the object image processor 400. Referring to FIG. 4A, an ‘Easy Authoring’ button 410 is currently displayed on the screen of the display apparatus 100. A button 405 of the object image processor 400 is provided to receive a command directing to display the image photographed by the object image processor 400 on the screen of the display apparatus 100. Accordingly, if the user selects the ‘Easy Authoring’ button 410, the display apparatus 100 perceives an intermediary figure from the inputted image.

FIG. 4B illustrates a situation in which an image 420, currently photographed by the object image processor 400, is displayed as the entire screen. Referring to FIG. 4B, the image 420 photographed by the object image processor 400 includes an intermediary FIG. 425. If the user selects a ‘capture’ button 430, the display apparatus 100 captures the image being photographed by the object image processor 400 as a separate image as illustrated in FIGS. 4C and 4D.

FIG. 4C illustrates a situation in which an Object Image Processor window 440 is displayed in response to selection of a capture button 430 of FIG. 4B, so that the image captured at a capture image display area 450 is loaded. The Object Image Processor window 440 displays in real-time basis an image photographed by the object image processor 400. That is, the Object Image Processor window 440 of FIG. 4C is the entire screen of FIG. 4B displayed as a window form.

When loading is completed, referring to FIG. 4D, the display apparatus 100 captures the image 420 displayed on the Object Image Processor window 440 as is, and displays the captured image on the capture image display area 450. The display apparatus 100 stores the captured image 420 as a separate file.

Additionally, if the user touches a delete button 448 which is an additional button with respect to the Edit button 445, the display apparatus 100 removes the Object Image Processor window 440 from the screen.

FIG. 4E illustrates the screen from which the Object Image Processor window 440 is removed. Referring to FIG. 4E, the captured image 420 is displayed on the capture image display area 450. As illustrated, the captured image includes the intermediary FIG. 425.

At this state, if the user selects the Easy Authoring button 410, the display apparatus 100 perceives an existence of the intermediary FIG. 425 in the captured image 420.

Referring to FIG. 4F, the Easy Authoring button 410 of FIG. 4E is automatically converted to ‘Switch to Board Screen’ button 415 of 4F. The ‘Switch to Board Screen’ button 415 receives a command directing to release Easy Authoring function. That is, the display apparatus 100 toggles between ‘executing’ and ‘releasing’ of the Easy Authoring function according to the Easy Authoring button 410 and the ‘Switch to Board Screen’ button 415. Although the button to receive a command directing to release the Easy Authoring function is named as ‘Switch to Board Screen’ button 415 in the example explained above, the button 415 may be named otherwise. For example, the button to receive a command directing to release the Easy Authoring function may be named as ‘Easy Authoring Release’ button. Alternatively, the name of the Easy Authoring button may be retained, but the form of the button can change. In this case, the user understands that the Easy Authoring button operates in a toggling manner, based on the effect that the form of the Easy Authoring button changes.

FIG. 4F illustrates the screen on which a Digital Object Insert icon 460 is displayed on the intermediary FIG. 425 according to a perception at the display apparatus 100 of the existence of the intermediary FIG. 425 in the captured image 420. The Digital Object Insert icon 460 receives a command directing to insert a digital object into the intermediary FIG. 425. Accordingly, if the user selects the Digital Object Insert icon 460, the display apparatus 100 carries out the process of inserting a digital object into the intermediary FIG. 425. The Digital Object Insert icon 460 may exist on the image of the intermediary FIG. 425, in the same shape and size as those of the intermediary shape 425. The display apparatus 100 may also carry out a process of inserting a digital object in a state that the Digital Object Insert icon 460 is not displayed, by responding to selecting of the intermediary FIG. 425 itself

FIG. 4G illustrates the screen on which Digital Object Type menu 470 is displayed. If the user selects the Digital Object Insert icon 460, the display apparatus 100 displays the Digital Object Type menu 470. Referring to FIG. 4G, the Digital Object Type menu 470 may include an image item, a sound item, a flash item, and a content item.

If the image item is selected from the Digital Object Type menu 470, referring to FIG. 4H, the display apparatus 100 displays an Image Object Select window 480. If a specific image 482 is selected from the Image Object Select window 480, the display apparatus 100 inserts the selected specific image 480 into a location where the intermediary FIG. 425 is displayed.

FIG. 4I illustrates the screen on which the selected specific image 482 is inserted into the location where the intermediary FIG. 425 is displayed. As explained above, if the user selects the ‘Switch to Board Screen’ button 415 after the selected specific image 482 is inserted into the location where the intermediary FIG. 425 is displayed, the display apparatus 100 finishes generating of the digital content.

FIG. 4J illustrates a situation in which the completed digital content 429 is displayed on the capture image display area 450. Referring to FIG. 4K, if a save item 492 is selected from the menu 490, the display apparatus 100 stores the completed digital content 429.

That is, referring to FIG. 4L, if the user inputs a save command with respect to the storing location selected through a storing location select window 494, the display apparatus 100 stores the completed digital content 429 at the selected storing location.

Then, referring to FIG. 4M, the display apparatus 100 displays a message window 496 to inform that the digital content is stored. Then, referring to FIG. 4N, if the user selects an OK button 498, the display apparatus 100 removes the message window 496 from the screen.

By the processes explained above, the display apparatus 100 receives an image photographed by the object image processor 400 and generates digital content using the received image. Accordingly, the user can photograph a hand-drawn picture on a paper sheet using the object image processor 400 and generate digital content on the display apparatus 100 based on the photographed image.

The process of generating digital content by receiving a previously-stored image and using the received image will be explained below with reference to FIGS. 5A to 5J. FIGS. 5A to 5J illustrate the process of generating digital content by receiving a previously-stored image and using the received image, according to an embodiment. The previously-stored image may include an image stored at the display apparatus 100, or an image stored at an external device. To use an image stored at an external device, the display apparatus 100 is communicably connected to the external device and receives the image from the external device.

FIG. 5A illustrates the screen on which a stored image file list 510 is displayed. Referring to FIG. 5A, the stored image file list 510 includes a specific image 520 which is the base of the digital content to be generated.
